Description

A kind of purple willow cuttage and seedling culture method

Technical field

The invention belongs to field of planting, be specifically related to a kind of purple willow cuttage and seedling culture method.

Background technology

Purple willow is a kind of important wicker plaiting article raw material of wicker plaiting article, is therefore a kind of important economic crops, and when purple willow is planted, the mode of cuttage and seedling culture that adopts carries out nursery more now, but during purple willow nursery, often directly carries out cuttage, but the survival rate of cuttage is not high.

Summary of the invention

The object of this invention is to provide the cuttage and seedling culture method of a kind of purple willow, improve the survival rate of purple willow cuttage and seedling culture.

The present invention is achieved through the following technical solutions:

A kind of purple willow cuttage and seedling culture method, comprises the following steps:

(1), cuttage planting soil process

Annual mid-February, application of organic fertilizers 1000kg/ mu, sodium bicarbonate 30kg/ mu, quicklime 20kg/ mu, urea 50kg/ mu, root of gansui 1.5kg/ mu, semen astragali complanati 0.8kg/ mu in planting soil, above-mentioned each raw material is evenly sprinkling upon in soil, then ploughing makes it fully mix with soil, planting soil is ploughed deeply 40cm, irrigates;

(2), the selection of cuttage branch and process

Selection diameter is 0.3-0.5cm, grow, be that the purple willow branch of 18cm is as cuttage branch with the length of axillalry bud, cuttage branch is put into treatment fluid and soaks 10min, described treatment fluid hands over youngster 2.6 parts by the root of kudzu vine 1.5 parts, the tuber of stemona 4 parts, Verbena officinalis 6.5 parts, horse by weight, fructus amomi 7 parts, reticulate millettia 3 parts, 100 parts, water mix and decocts the cooling fluid of 1h, then adds zinc gluconate 2.5 parts formulated; After immersion completes, stand-by for cuttage branch is carried out cutting, from top, axillary bud growth direction 2.5cm horizontal truncation, be cut into inclined-plane from axillalry bud bottom 4cm;

(3), the process of cuttage branch end

Use methyl α-naphthyl acetate 500 times of solution to process the fracture at cuttage branch top, cuttage branch bottom bevel uses the mixed liquid dipping process 20min of 3 parts, potassium nitrate, 4.5 parts, urea, 2 parts, sodium bicarbonate, 40 parts, water;

(4), cuttage

Annual late Febuary carries out cuttage, and during cuttage, by downward for the cuttage branch inclined-plane handled well, axillalry bud upwards carries out cuttage, and cuttage branch inserts soil 4-5cm, every cave cuttage 3-5 strain, and 3-5 days after cuttage, sprinkles the ash that 0.5cm is thick;

(5), manage after cuttage

After cuttage, use rice straw mulching on soil top, control sunburn, waters 1 time, after sprouting, then waters for after branch cutting 3 days, and carry out applying fertilizer, weeding, insect protected operation.

Beneficial effect of the present invention: purple willow cottage method provided by the invention is by improveing the technique of cuttage, increase seedling density, and purple willow nursery stock growing way is even, survival rate is high, solution is used to process, improve the resistance against diseases of purple willow seedling, owing to shortening the length of cuttage branch, reduce bacterial number on kind of bar, reduce the probability that nursery stock morphs, its adaptability is strengthened, promote the survival rate of nursery stock, and carry out nursery in the last ten-days period in February, the defect that before overcoming, survival rate of seedling is low before March, and the last ten-days period in February carry out nursery, to stagger the peak of purple willow nursery, in planting process, cost of labor also reduces greatly, and nursery stock is when contrasting with conventional method, because growth time is long, the seedling brought out than conventional seedbed system method after listing is large, economic worth is high, the present invention simultaneously uses organic component as fertilizer, can not spoiled soil active, the long-term nursery of soil also can ensure its good activity, keep output and the survival rate of nursery.

Embodiment

A kind of purple willow cuttage and seedling culture method, comprises the following steps:

(1), cuttage planting soil process

Annual mid-February, application of organic fertilizers 1000kg/ mu, sodium bicarbonate 30kg/ mu, quicklime 20kg/ mu, urea 50kg/ mu, root of gansui 1.5kg/ mu, semen astragali complanati 0.8kg/ mu in planting soil, above-mentioned each raw material is evenly sprinkling upon in soil, then ploughing makes it fully mix with soil, planting soil is ploughed deeply 40cm, irrigates;

(2), the selection of cuttage branch and process

Selection diameter is 0.3-0.5cm, grow, be that the purple willow branch of 18cm is as cuttage branch with the length of axillalry bud, cuttage branch is put into treatment fluid and soaks 10min, described treatment fluid hands over youngster 2.6 parts by the root of kudzu vine 1.5 parts, the tuber of stemona 4 parts, Verbena officinalis 6.5 parts, horse by weight, fructus amomi 7 parts, reticulate millettia 3 parts, 100 parts, water mix and decocts the cooling fluid of 1h, then adds zinc gluconate 2.5 parts formulated; After immersion completes, stand-by for cuttage branch is carried out cutting, from top, axillary bud growth direction 2.5cm horizontal truncation, be cut into inclined-plane from axillalry bud bottom 4cm;

(3), the process of cuttage branch end

Use methyl α-naphthyl acetate 500 times of solution to process the fracture at cuttage branch top, cuttage branch bottom bevel uses the mixed liquid dipping process 20min of 3 parts, potassium nitrate, 4.5 parts, urea, 2 parts, sodium bicarbonate, 40 parts, water;

(4), cuttage

Annual late Febuary carries out cuttage, and during cuttage, by downward for the cuttage branch inclined-plane handled well, axillalry bud upwards carries out cuttage, and cuttage branch inserts soil 4-5cm, every cave cuttage 3-5 strain, and 3-5 days after cuttage, sprinkles the ash that 0.5cm is thick;

(5), manage after cuttage

After cuttage, use rice straw mulching on soil top, control sunburn, waters 1 time, after sprouting, then waters for after branch cutting 3 days, and carry out applying fertilizer, weeding, insect protected operation.

The present invention is used to carry out seedling growth test in Funan County, test is carried out 500 mu of Tanakas, method of the present invention is used to carry out nursery, every mu of nursery amount reaches 62300 strains, survival rate is to 95.8%, and be all generally the last ten-days period in March or April carry out nursery at North-Anhui district, the present invention carries out nursery in the last ten-days period in February, do sth. in advance the time of nursery, and ensure that the survival rate of nursery, make in the identical plantation period, the strong degree of nursery stock of the inventive method nursery and size are obviously better than using prior art to carry out the purple willow seedling of nursery, and survival rate is higher after plantation, nursery stock is worth higher.

The present invention uses two step cuttage branch treatment steps in step (2), (3), improves 7.2% than the survival rate of seedling of use one step processing method.

Do not use the treatment fluid of step (2) to process, directly late Febuary North-Anhui district carry out cuttage and seedling culture, survival rate is often lower than 80%.
